Once the first backup image has been successfully authenticated, the second backup image may be updated by the most recent copy of the first backup image. In another embodiment, the second backup image is the default image stored with factory settings. In this embodiment, the default image is an authenticated and tested image that is stored in the memory during the manufacturing process.

FIG. 5A illustrates a schematic block diagram 500 of a plurality of partitions 502, 504, 506, 508, and 510 of a storage device (for example, storage device 308) for storing a first backup image and a second backup image, according to one embodiment of the present invention. The partitions, as shown, include a first partition 502 storing the active image, a second partition 504 storing the first backup image, a third partition 506 storing the second backup image, and other partitions such as a fourth partition 508 and up to an nth partition 510. In the embodiment shown in FIG. 5A, each partition may include one or more clusters, and each cluster may have one or more sectors. Each sector may store a part of backup data for restoring the active image, the first backup image, and the second backup image. The active image stored in the first partition may be utilized for initiating a booting up process for the intelligent communications device 102.

Referring now to FIG. 5B, in one embodiment, the active image is stored in a first memory 512, the second backup image in a second memory 514, and a third image in a third memory 516. In this arrangement, a software subroutine may be provided that operates to swap the active image of the first memory 512 with the first backup image of the second memory 514, to boot the operation of the intelligent communications device 102 into a steady state.

In one embodiment, the intelligent communication device 102 may interface with one or more smart grid devices. The smart grid devices may communicate with the intelligent communication device 102 through subroutines and/or programs. The subroutines or programs may access the memory 308 of intelligent communication device 102 making it vulnerable to the malicious attacks. Likewise, the internal program and subroutines may malfunction due to certain abnormal conditions, such as but not limited, to high temperature of the intelligent communication device 102, failure of one or more components, memory leaks, program contamination with external virus, worms, time bombs and other malicious programs. The intelligent communication device 102 may include a self-healing and self-protecting mechanism that may allow it to reset and recover from malicious attacks, viruses, and other faults.

The kernel may include processes, subroutines, programs, subprograms and other executable instructions being executed or waiting for processor time. Monitoring of these processes, subprograms, routines, subroutines, sub-programs will ensure proper functioning of the intelligent communication device 102. In addition, the monitoring also ensures that all the processes in the execution queue are executed by the processor 310 based on pre-specified criteria such as but not limited to the priority attached to each of the processes. The intelligent communication device 102 may fail to execute one or more processes due to certain conditions such as unusual long time for executing a single process, deadlock, exceptionally large programs that cannot fit into memory, resource constraints, or other conditions. In such situations, the kernel may initiate a backup and recovery process for recovering from an unusual state to an operational state.

The backup and recovery process may be stored into the memory 308. In one embodiment, the backup and recovery process is be stored in a RAM, ROM, primary memory, hard disk, flash memory, or a computer-readable medium associated with the intelligent communication device 102. For managing the recovery process, the intelligent communication device 102 initiates process 600, which monitors one or more conditions to ensure the performance of the intelligent communication device 102 in the operational state. In an embodiment, the process 600 is an open source routine or an application program for ensuring the performance of the system in the operational state.

In an embodiment of the present invention, one or more subroutines/programs monitor the charge on one or more capacitors to examine the health of the intelligent communication device 102. Alternatively, the one or more subroutines examine the health of the active and passive components based on the charge on one or more capacitors. Similarly, the intelligent communication device 102 may monitor the power supply feed to each of the circuitry to ascertain the performance and health of the intelligent communication device 102. A power failure may send an alert to the server or a central agency about a power outrage. The subroutines may facilitate in circumventing the condition of abrupt shutdown. A power backup facility such as but not limited to battery may be utilized to provide power to the intelligent communication device 102 during a power failure. In one or more instances, the subroutines may determine that it is dangerous to operate the intelligent communication device 102. To avoid data loss in these scenarios, the subroutines may shutdown the intelligent communication device 102.

Referring to FIG. 6, operational steps of a routine 600 for initiating a recovery of the active image are shown, according to an embodiment of the present invention. The routine 600 starts at step 602 and immediately moves to step 604. At step 604, the active image is stored in the memory 308. This active image corresponds to the default image, which is validated to be an authentic boot image. The first backup image and the second backup image also store default images. The routine 600 may be operative to receive upgrades for changing one or more of the active image, first backup image, and second backup image.

The intelligent communication device 102 may include an update facility, which may update the routine 600 associated with the intelligent communication device 102 with the new updates. The update facility may continuously instigate the server for availability of updates. As soon as the updates are available, the intelligent communication device 102 may download the updates and apply it for upgrading the intelligent communication device 102.

The intelligent communication device 102 may receive updates from the server prompting it to update itself with latest software patches/updates. In an embodiment of the present invention, the updates may be first applied to the active image; the active image may try to boot itself into an operational state; a failure to boot the intelligent communication device 102 into the operational state may initiate a recovery routine. In this aspect, the recovery may be performed from the first backup image. During the recovery, the routine 600 may replace the active image with the operational first backup image. This may be considered as a simple recovery operation.

In an alternative embodiment of the present invention, the updates may be applied to the first backup image; the updates may be validated by booting the intelligent communication device 102 from the first backup boot image. If the intelligent communication device 102 can be successfully booted after applying the updates then the updates may be applied to the active boot image else the updates may be discarded. Otherwise, if the intelligent communication device 102 fails to boot properly from the first backup image the updates may be discarded. In this scenario, the intelligent communication device 102 may boot from the active image, initiate a backup routine to create a new copy of the first backup image, which may be utilized to restore the intelligent communication device 102 later, in case of a disaster.

The second backup image may store the default image (factory-applied image) in an embodiment of the present invention. In another embodiment, the second backup image may store the last backup image, which is a valid good image. It may be understood that the last known good backup may not always be equivalent to the first backup image.

A failure to boot correctly into the operational state may prompt the recovery routine to replace the failed active image with the default image. It may be noted that the terms ‘operational state’ and ‘steady state’ both refer to normal operation of the intelligent communication device 102 and are used interchangeable in this description. In another embodiment of the present invention, the recovery subroutine/program/routine loads and replaces the failed active image with the second backup image after the intelligent communication device 102 has failed to recover, by applying a recovery routine through the first backup image.

At step 606, an attempt to boot the intelligent communication device 102 into the operational state through the active image is initiated. At step 608, it is determined if booting of the intelligent communication device 102 is successful. If the intelligent communication device 102 boots successfully, the routine 600 proceeds to step 622 and boots the intelligent communication device 102 into the operational state. Otherwise, the routine 600 proceeds to step 610. At step 610, the intelligent communication device 102 attempts to boot from the first backup image. At step 612, the it is determined if the intelligent communication device 102 had successfully booted. If the intelligent communication device 102 can be successfully booted, the routine proceeds to step 622 and boots into the operational state. Otherwise, the routine 600 moves to step 614. At step 614, the routine 600 attempts to boot the intelligent communication device 102 from the second boot image. At step 616, the routine 600 determines if the boot from the second backup image was successful. If the intelligent communication device 102 is successfully booted from the second boot image, the routine may immediately move to 622. Otherwise, the routine 600 proceeds to step 618. At step 618, a determination is made of the number of attempts to boot the intelligent communication device 600 into the operational state. In this embodiment, a watchdog is provided to keep track of the number of reboots already attempted. In an embodiment of the present invention, the watchdog is be a software counter or a hardware facility. If the number of reboots attempted has exceeded a threshold value then the default image is restored and the intelligent communication device 102, to allow the is intelligent communication device to boot into the operational state. Otherwise, the routine 600 continues to attempt booting the intelligent communication device 102 using the first backup image and the second backup image.

In one embodiment of the present invention, one or more types of memory are utilized for the first backup image and the second backup image. For example, the first backup image may be executed on the secondary memory and the second backup may be executed on the memory located outside the intelligent communication device 102. Similarly, in another embodiment of the present invention, both the first backup image and the second backup image are executed on different secondary memories. For example, the first backup image may be created on a hard disk and the second backup image may be performed on a flash memory.

In various embodiments, the one or more memory may be an EPROM, an EEPROM, a hard disk, a flash memory, a CD-ROM, a DVD, a RAID or other types of storage devices.

Referring again to step 622, once the operational state has been attained, the intelligent communication device 102 initiates necessary action for recovery. In an embodiment of the present invention, the intelligent communication device 102 utilizes the first backup image to overwrite the corrupted active image, if the intelligent communication device 102 can successfully boot from the first backup image. Alternatively, the intelligent communication device 102 utilizes the second backup image to overwrite the corrupted active image and the corrupted first backup image, if the intelligent communication device can successfully boot from the second backup image.

In another embodiment of the present invention, the intelligent communication device 102 may initiate a subroutine for booting the intelligent communication device 102 into the operational state. In this embodiment, the intelligent communication device 102 attempts to boot into steady state by alternatively booting form the first backup image and the second backup image until the subroutine is able to boot into steady state. This may be referred as ‘progressive boot’. In an alternate embodiment of the present invention, the subroutine utilizes the first backup image to boot into the operational state until an error is encountered. At this point, the subroutine tires to perform the subsequent steps from the second backup image. If such a boot is successful, then the subroutine creates a new image based on amalgamation of the partial first backup image and the partial second backup image. At step 624, the routine 600 ends.

In one embodiment of the present invention, the first backup image and the second backup image are stored in a compressed format. Any standard compression techniques may be utilized to compress the first backup image and the second backup image. The compression of backup image may facilitate storing of more than one backup image into the memory 308.

Referring to FIG. 7, multiple versions of the first backup image and the second backup image are depicted, according to one embodiment. First memory 514 is shown as having two different copies of the first backup image created at different dates and time. As an example, the first backup image-T1 702 may have been created on Dec. 25, 2009 at 3.00 p.m., whereas another different version of the first backup image-T2 704 may have been created on Dec. 29, 2009 at 4.00 p.m. Similarly, multiple versions of second backup image may be created. For example, third memory 516 may store two different backup images such as a second backup image-T1 706 created at date D1 and time DT1 and a different second backup image-T2 created at date D2 and time DT2. Although only two backup images have been shown in the embodiment of FIG. 7, those skilled in the art will appreciate that multiple backups in compressed and non-compressed forms may be created in alternate embodiments without deviating from the scope and spirit of the invention.

Now referring to FIG. 8, in one embodiment of the present invention, the multiple backup images may be utilized to boot the intelligent communication device 102 into the operational state. As shown, the second memory 514 includes include multiple copies of the first backup image created at different times. As an example, the second memory 514 may include a first backup image-T1 702 created on Aug. 23, 2010, a first backup image-T2 704 created on Aug. 24,2010, and a first backup image-T3 802 created on Aug. 25, 2010.

The first backup image and the second backup image may require authentication for execution. The first backup and the second backup image require validation before a recovery is performed. For example, the digital management rights associated with the first and the second backup image may require automatic authentication from a remote server to execute the recovery operation. Alternatively, the recovery operation may be performed within the protected mode that may boot the intelligent communication device 102 with minimum set of operating services.
